D., University of California, San Francisco, School of Medicine, San Francisco, California BRIAN MITTMAN, PH.Remeron is usually given as tablets 15 - 45 mg/day, administered in a single dose, preferably in the evening before sleep, with or without food.Dosages are increased, if necessary, slowly over one to two weeks.Mirtazapine is also a good choice in depressed patients with significant anxiety or insomnia. Cost to the patient will be higher, depending on prescription filling fee*—Estimated cost to the pharmacist based on average wholesale prices, for one month's therapy at the lowest usual dosage level, in Red book. Selective serotonin reuptake inhibitors (SSRIs) have become the drugs of choice in the treatment of depression.3 Generally, either the older tricyclic antidepressants or the newer antidepressants are used for second-line therapy.4 During the first few years of introduction to the U. market, it is reasonable for an antidepressant such as mirtazapine to be reserved for use in patients who do not tolerate or do not respond to initial therapy with SSRIs.Although mirtazapine has been used successfully in Europe for a number of years, its place in the care of patients with depression in the United States has not yet been established.*—Estimated cost to the pharmacist based on average wholesale prices, for one month's therapy at the lowest usual dosage level, in Red book. Mirtazapine is a tetracyclic piperazinoazepine, which has a different structure from any other currently used antidepressant.Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior.
Families and caregivers should be advised of the need for close observation and communication with the prescriber.
Caution should be used in the elderly because paroxetine is the most sedating and anticholinergic of the selective serotonin reuptake inhibitors The elderly are prone to SSRI/SNRI-induced hyponatremia; monitor closely 65 years In children and young adults, risks must be weighed against the benefits of taking antidepressants Patients should be monitored closely for changes in behavior, clinical worsening, and suicidal tendencies; this should be done during the initial 1-2 months of therapy and dosage adjustments The patient’s family should communicate any abrupt changes in behavior to the healthcare provider Worsening behavior and suicidal tendencies that are not part of the presenting symptoms may require discontinuation of therapy This drug is not approved for use in pediatric patients Clinical worsening and suicidal ideation may occur despite medication in adolescents and young adults (18-24 years) Use caution in patients with bipolar disorder, seizure disorder, history of suicidal thought/behavior Life-threatening serotonin syndrome reported with SNRIs and SSRIs alone; also with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, and St.

Physicians who are concerned about the risks of elevated lipid levels and agranulocytosis may choose to reserve mirtazapine as a third-line choice.
It is particularly useful in patients who experience sexual side effects from other antidepressants. Cost to the patient will be higher, depending on prescription filling fee As with any new drug, mirtazapine's place in the treatment of depression is not yet clear.
It enhances central noradrenergic and serotonergic activity by blocking alpha10Mirtazapine is well absorbed without regard to food intake.
